here are some pics
I would describe the effect more like a sandpaper texture. How does the ps look.
Those sand like textures reflect tiny bit of colors so that's why it's called prism effect. Most anti-glare screen protectors have this effect and I can actually see it in the picture you posted. It's kinda hard to measure how much in that picture but PS does have a little bit of that, too, but, it's very minimum and I never notice it unless I think about it. A lot of past reviews and comparisons universally concluded that the (prism) texture is minimum on the PS AG so that's why I went with it. However, I've never seen a direct comparison between the SM and the PS side by side so I'm definitely curious about the difference in both.
Mine is just another opinion, but I tried both of the clear and matte versions of the Splash protectors. If you are looking for something decent at a reasonable price, both are fine options. I did not personally like the matte version though.
I ended up installing the PowerSupport clear. It is better quality and a better fit but cost about $30 for one vs $20 for three. If you are perfectionist, the additional cost of the PowerSupport film is money well spent; if not, the Spash protectors are fine.
I thought the Splash Masque anti-glare was horrible. Glad they do work for some people, but the blurry text and the constant air bubbles drove me nuts. While I took my time, just could not install without some kind of air bubble.
I've spent so much on accessories, I'm a little wary of paying $30 for the Powersupport and/or Moshi's Anti-Glare iVisor, so I'll just wipe down after each use for now.
