Hi everyone! Some updates from me.
Some months ago bought an LG VA panel (can look up the model but I dont think its important) and it wasn't good on the eyes (high herz too).
Good news now, switched my OnePlus3 to Honor 90 recently, and can confirm its not causing problems. Color scheme set to Normal instead of Vivid, highest resolution and 60 hz option is completely fine. 120 hz im not sure about yet, just switched to it to test, as initially i started with low res and low refresh rate. Will report on the rate, but even if only 60hz is good, its still worth a try for you.
