What about component.getTier() method?

[MoonlightOwl]

It would make tier-dependent Lua code easier to write, and more consistent too.

Methods like gpu.maxDepth() are not always obvious.
And in this case it also does not allow to distinguish between a screen tier and GPU tier.

How would you want to get the tier of things that aren't components? Would need to be part of deviceinfo then.

[payonel]

this would be for device info, indeed

I have had the problem just now.
As a workaround I have to offer this function:

Of course, this also has the problem that is indistinguishable, who limits the color depth or resolution.
