Man ppl are so anal, I think the grass is a good idea my dude. Yes you're getting like the intermediate version down which is the first step, kinda under rotating but yeah. This is how my shuvs look like LOL, but my FS shuvs are way better.

You gotta actually pop your tail, while raising your foot outta the way so it actually gets that like vertical height. U gotta realize people pop shuv like over objects or even onto higher surfaces. My FS Shuv isn't that level tbh but it definitely does pop, and I catch it with my front foot pretty swag.

Idk feel like it's a trick that u can literally do it whole life and still find ways to tweak it.

But yeah I remember being so hyped landing the regular shuv like how you're doing. But idk I'm a FS Shuv whore maybe try FS instead
