I was wondering if anyone knows if there is a difference in paint quality when it comes to Premium Paint vs Regular paint.

From Acura's website it mentions the following:
Anyone knows the paint thickness difference between premium vs regular?

Generally speaking typical modern car paint is:

3 stage is base, color, clear

4 stage or premium is Base coat, mid or pearl coat, tinted clear, and clear coat. Variation in 4 stage terms might be base, pearl, color, clear with pearl and color might swap positions. It’s also common to add additional coats of clear to add depth.

Some manufactures still use 2 stage base color ( no clear) with some colors.

E-coat, chip guard and other special primers are below the base.

More layers usually mean more thickness, I have no paint thickness gauge at my disposal. I can ask a detailing group I am on.

That would be great! Thank you!

So they say that the major difference is that there Is color or tint in the clear. Same or similar thickness.

I feel left out of the "Premium Paint" party since I have Lunar Silver — and that's not mentioned among the premium paints. (It sure looks premium to me, though.)

Best-looking silver I've seen.

4 stage vs 3 stage…….extra stage significant more cost, extra coat ( stage is slightly thicker) often noticed when the body shop repair is higher due to the extra and labor.

Pearl paint material is a much higher cost.

Really what matters from a detailing perspective, is how thick the clear coat is. As that is the layer you will be doing any sort of paint correction on. No one wants to get to the color layer, on a modern car paint. Once you get there, it’s a pain to clear the panel again without laying down the color layers to match.

So, best advice is always the least abrasive is the best. Kind of the advantage of a ceramic coating, as once the paint correction is done, that super hard coating is harder to scratch.
