I agree it's headed in that direction but I don't think OP is just talking about regular shots or step backs only. I think he's saying that guys like Curry don't get the proper grade for shots they take on the regular when compared to other shooters.
EX: You can have two good three point shooters, say Curry and Korver. While Curry excels at making off the dribble shots, pull up jumpers, step backs (basically everything lol) and Korver really excels at the catch and shoot, both players will receive the same grade for shots they shouldn't (ex: Curry should receive a much higher shot grade/letter grade for an off the dribble shot than Korver, but because they both have high shot ratings it is unlikely that he does.)
The difference between what you said is that DeAndre will get a bad grade no matter what due to his 3pt rating, but if you take someone with a good 3pt rating who isn't good at off the dribble shots and put them next to someone with a good 3pt rating who is good at off the dribble shots you'll see they receive similar grades.
I went into blacktop mode 1v1 with Korver and Curry and controlled both (difficulty superstar sim):
I took the defender and moved them away from the ball handler towards the free throw line without moving the ball handler from their default position on standing deep threes.

Personally I noticed Curry receives a much higher grade on moving threes which is very good but Korver received a far too high grade for step backs. Not sure how good Korver is at pull-ups in transition but I know he's pretty much just a catch and shoot marksman so his grade seems a little surprising. (

You can see that Curry and Korver both get very high grades for step back threes while only Curry gets high grades for moving threes (most likely due to Curry's 95 moving three compared to Korver's 87 moving three). The most surprising part was how high of a grade step back threes got. Curry's moving three shot grade could possibly be boosted, a C- seems kinda low for a guy of his shooting prowess but I'm not sure what a C- translates to percentage wise so it could be good.
It seems like the discrepancy in shot grades is present, however further detail needs to be added for certain players and shots (Korver shouldn't excel at step backs threes the way Curry does).
Also agree with Hanz's post, if you get a player with two red rings (in rhythm/hot) you'll see they make a lot more shots.
I have a pretty lengthy video of me doing all this stuff if anyone wants it, and sorry if the post is a little rambly I'm writing this at 6 AM.
Here are some things in real life that I believe Curry couldn't really do in 2K (at least not as often as he does):

Curry is the exception to "well he doesn't do that often it's a rare shot and you hit rare shots like that in 2K" because he does do that often and he's the best shooter in the NBA right now.
That's why we need a way for players like him to excel at hitting shots like that while others don't. Unforunately I think bringing in signature styles like this will have us see more players playing hero ball and taking insane shots when only one guy in the NBA can hit those things consistently, although I don't think it should be shied away from because of those bad apples.
