Every human is different so some may see it too dim. Some, like me find it just right. Some will find it too bright... so find the right balance for your individual taste is my suggestion.
You also using M3 iMac, after Just one year your screen suddenly will have flickering lines appear at the bottom? I used to post this. If you go search around or even in official Apple community forum a lot mention this Flaws from Apple come M series iMac. even Mac rumours also report an article come M1 iMac suddenly have lines appear upon using just after one year.
I still can use it as the lines just at the bottom. I do ask Apple and they claim need to Pay to replace the screen. There are report also claim even you get fix after one year or so the flickering lines will appear back.

I bought my iMac M3 December 2023. So it's coming up to 3 years in December 2026. Yes I'm fully aware of that sudden screen failure as I've posted that link from the Apple Community Forum that Apple closed! They closed it as more and more M1 iMac users are reporting this failure within the 2 year mark of iMac M1 users.

Apple Silicon iMacs appear to suffer from screen deterioration after two years — flood of user complaints hit Apple Community forums
Users complain of horizontal lines appearing and staying on the screen about two years from the date of purchase.
Yeah they close that thread. So yours M3 also have suddenly lines appear at the bottom? I still using it as typing here. No doubt is a bit .... especially if watch Movie on full screen... I actually thinking go pay to get fix at Apple store. I know a lot get rejected for free repair. i see the price man, I guess. I just live with it using it. That price to get fix, i can just top up a bit to get an iPad Pro. Some will say even cheaper to get a mac mini just that need to get another monitor.I bought my iMac M3 December 2023.

Not an M-iMac owner — Studio Display + Mac Studio here — but the auto-brightness pipeline is the same ambient sensor on both. I leave it off for the same reason kagharaht mentioned: it drifts during the day and that's death for anything color-critical. Mine sits around 60% during daylight, dropped a bit in the evening with Night Shift on. For creative work especially, calibrate once with a colorimeter and lock it there. Auto will fight your reference white point every time the lighting changes.
