Switched from Era100 Surrounds to 300s and not impressed

OK hope i don't take too much flack for this post. I have an Arc Ultra, Sub Gen 3 and I juat switched from Era 100s to Era 300 surrounds and I honestly cant tell much difference.

Ive tried multiple movies that are recommended to get some good Dolby Atmos (Top Gun 2, Avatar 2, Bohemian Rhapsody). I just don't notice any extra rear immersive height audio.

I've run advanced true play and ive set the height to +5.
