The IPS I had was also 60% srgb but it still seems to have a very high intensity in the colors, the colors to navigate there are many strong colors distracting the attention and it is exhausting to be for hours with neon colors everywhere, not even something as simple as the task bar is free from that intensity no matter how you configure it, it seemed to come out of a toy store, all without exaggeration.
I think IPS cell phones also have the dreaded "ips brightness" but apparently because they are smaller screens they do not end up stressing the eyes, but I did notice that at maximum brightness my vision was at its limit and I needed to lower the intensity to about 20-30% to be able to look at it. I do not think it is a genetic problem, besides the fact that the eyesight is trained for one screen or another does not go through genetic factors. In my country I found $2000 gaming notebooks with TN screens, but according to the seller "the screens were very bad" and he recommended an OLED instead. How can I believe him? I've been using them all my life and with each one, no matter how different they were from one model to another, I have never had the problem that IPS has given me, nor have I had the discomfort of OLED contrast.
If you tell me you want it for gaming, well... the OLED I tried was incredible with PS2 emulators, even better than a tube TV, but sometimes there were glares that shouldn't appear at such a high intensity, and in PC games the color intensity was already starting to be a disaster, the image ended up looking fake in some RTS menus because of the color intensity, but with TN screens it really felt natural. I think in the end what you should miss the most are the deep dark and deep shadows
