which one would be better, have higher picture quality, and more reliable + supported ?
This is actually very simple to answer.
Are you running the AppleTV through a Lumagen processor for dynamic tone mapping? If the answer is yes, get the AppleTV. If the answer is no, a MadVR solution will blow the AppleTV out of the water when it comes to image quality (assuming your display is up to the task). If you don't plan to use dynamic tone mapping or other image processing, it doesn't matter, just get the cheaper solution.
It's a video processor used for all things image processing and calibration (see: http://www.lumagen.com/testindex.php?module=radiancepro_details). Basically, you attach every source device to it and the output is attached to your display/projector. The processor can handle the full calibration and does things such as scaling, converting aspect ratios, handling anamorphic lenses for projectors, framerate conversion, and much more including the mentioned dynamic tone mapping. It's very common in full installations to get the best possible video quality.What the heck is a Lumagen processor please? Thanks. Sorry.

MadVR is also for optimizing video quality and does dynamic mapping, but it only does it for the HTPC it's installed on. You can't use it with external devices such as AppleTV, a game console or any other playback device. An external video processor allows to attach external devices to it.
Let me point one thing out, since some things have been mentioned by others, which I think completely fail the question or the question is not the right one. MadVR is all about video processing and getting the best image quality possible. It has absolutely nothing to do with what source you're using for playback (NAS files, ISO, Plex, ...) or how you organize your library by TV shows, movies, various genres (actors, sci-fi, action, horror, etc.) or how you navigate your library. The one and only purpose of MadVR is applying specific settings for video processing. In addition you still need video playback software such as Kodi and others. The latter is what Infuse on an AppleTV does.
AppleTV with Infuse is a simple media player. You can use it to organize your library and play your media from different sources, add metadata and so on. It has nowhere near the capability to customize your video processing as MadVR has, nor does it have the quality of videoprocessing as an external processor or MadVR.
So the question is really, do you only want to organize and playback your collection? Then get the AppleTV.
Or do you want the absolute best video quality possible? Then get the HTPC and MadVR and a media player software that can organize your library (or a Lumagen in addition to an AppleTV). Just be aware, in order to take full advantage of MadVR, get a Nvidia GPU for the HTPC as some filters require a lot of processing power. Also consider, MadVR usually requires custom tweaking to get the best out of it. This is not plug & play, i.e. not downloading, installing and you're done. You will have to tweak settings.
...nor does it have the quality of videoprocessing as an external processor or MadVR.
How much better depends on what you're looking at. From barely visible to night and day. That is assuming your display device doesn't screw things up. Some displays have further processing that can't be turned off and mess things up. With projectors, lenses that soften the image can mess things up, so can eshift/4k enhancement. And yes, it's for all kind of source material.I'm curious – how much better can it be? Is this difference in quality for all kinds of sources – for example a 1080p Blu-ray – or is the difference more easily seen with 4K HDR materia?
Anything you describe can be done with a HTPC as well. I agree about Windows, but using a HTPC is not about having a normal streaming box.About HTPC I know little to nothing.
And this is plain wrong, sorry. Any streaming box can provide the same quality as a regular player, ATV4k, Nvidia Shield, etc. As I've pointed out before, a HTPC running MadVR or a dedicated video processor will allow to optimize the quality further than any streaming box or dedicated player can. This is just another step up in quality. What a HTPC does is save you around around $6.5k for a Radiance processor to get an AppleTV, Shield, etc. to the same level of quality as a HTPC. There will be an external MadVR processor soon which will also be an option, but I'd be surprised if it's under $4k.And then if one really wants quality is better buying an UHD BR player.

You can get better motion handling, dynamic tone mapping, artefact reduction/removal, aspect ratio conversion, processing for anamorphic lenses and so on and so forth. Even if your source is already the native resolution of your display device and the native frame rate, dynamic tone mapping makes a night and day difference, because the whole thing is calibrated specifically for your display chain. For lower resolution sources, you can select different interpolation algorithms and so on. Have a look at the thread I linked in a previous post and go from there. This is not specific for HTPCs, as good video processor in the chain will do the same/similar things.But in general? With the UHD BR player one knows to always get the highest available bitrate, and there is no algorithm that can recover the data lost due to lossy compression. Honest question.

Check out the first two messages on page 3 of this thread. Absolutely sums up my experience. Once it's up, running and fully calibrated, there's no way back. I've never heard of a person going back from MadVR/Lumagen system to one without it.
Any decent display will show the difference. Take a LG OLED, Samsung QLED, Sony Z/900/800 series, TCL, projectors from Sony, JVC, BENQ, Epson, etc. Of course a £30k Sony will show it too, just like a Barco Thor or the upcoming Christie Eclipse which will probably be in the $600k range. But it doesn't have to be that expensive. A $200 TV from some non-name Chinese manufacturer... probably not.Your reports are fascinating however, what kind of monitor screen would show all of these differences?
Nothing to be convinced about. Do a A/B comparison, done.I'm seriously not convinced that any domestic TV screen will show the difference.
Of course you can watch a film that way, display blue colors in green and what not. It all works. If you don't care about quality, don't waste your time. Anyone who cares about quality will calibrate their system or simply have someone do it for them. Anyone who wants the best possible quality is adding a video processor or HTPC with MadVR. Whatever rocks your boat, do it. This thread started with the question for higher picture quality and if you want the best with consumer electronics this is the way to go and makes a huge difference to just plugging things in. As I've pointed out, MadVR in particular requires experience and tweaking. If you don't want to waste your time, hire a professional to do it. Most people who have done it consider hiring a professional calibrator a worthwhile investment. But again, if you don't care about image quality just keep watching and don't think about it.Your way sounds harder than when I studied for my MSc and is kind of the exact opposite of the Apple ethos where everything is kept as simple, easy to use / humane as possible and 'just works'. (plus of course, multi platform in this decade is essential to me). And that's how something as basic and simple as watching a film should be.

I'd say yes. Years ago I used to run a VT30 with an external processor and thought it was worth it. Just keep in mind, your display has a 8-bit panel and is limited to Rec709. What you will get is better scaling for non-native sources and better HDR to SDR mapping.Do you think my Panasonic V20 plasma TV from 2010 will benefit?
