Do you guys genuinely notice the difference between TB400 and P1000 in games?

I've had my 321URX set to HDR P1000 since I bought it in March. I'm only now reading about the dimming concerns with P1000 (ngl I muted this sub after I made my purchase). Out of curiosity, I tried comparing TB400 to P1000 in Cyberpunk and Ghost of Tsushima. Granted, it's kind of a pia to switch back and forth between the two, but I was completely unable to find any noticeable instances of dimming in P1000.

Those who prefer TB400 over P1000, could you please point me to a game to compare the two in, or show off some comparison photos between the two? I know dark games benefit from P1000 and brighter from TB400 yada yada but I just want to set it to one mode and forget it, I cba with overthinking this
