RX 6800XT with 72CU vs 36CU and similar clock speeds is only 29.4% faster than PS5, while 3070 is 8.6% faster so it's safe to say PS5 is comparable to 2080 Ti and 3070 in ray tracing performance.
This solidifies that PS5 is using a custom RT solution vs RDNA2/Xbox SX, that's why RT is better on PS5 vs XSX and 6800XT is embarrassingly closer to PS5 than Xbox One to PS4!
You didn't watch or listened to the entire video.
1- PS5 RT on shadows only, and its disabled on some scenes for performance reasons.
2- Some PC version settings cannot go low enough to match PS5. Alpha effects in particularly.
Based on this, the only "weird" thing is the delta to the 6800XT. The rest of your post is not factual nor do the results point towards your conclusion. On this game, its between 2070S~2080. Its good enough, so take it as a good thing.
