Mine are both done as well, they don't sit as flush due to the extra padding and covering. So if you manage to get a matching offcut of leather you can send it off to paint matching place instead. I did that to get perfect match and sheen for speaker grilles, seatbelt guides, sail panels, kick panels. etc. Was there a certain paint you used for the dash grab handle, that looks perfect.
Apart from the glovebox door, and probably the steering column panel if you said the same, the rest looks good with just a slight and subtle change of shades throughout. Once you start matching a few more areas, the parts that don't match look like they are errors! Once I replaced a few of the camel tan parts on mine and retrimmed a few more, I basically had to finish anything that wasn't. It'll feel like slipping into a caramel thickshake when done, not sure that's a good thing, but smells so nice. It dated from a time when replacement door trims and seatcovers were not a thing, plus the custom touches and of course, RHD dash. There's things I'd change, for sure if starting from scratch.
I'd perhaps try some fine flexible filler for yours before it got to that stage, combined with some colour-matched touchup just wiped over the join, make sure it's well clean of any oils and protectants first. Too nice to cover just yet. Perhaps a dash or upholstery place might have some tips, the type that touch-up cracks in leather and vinyl.
