Smoothed — your colour kept, grain gone

You were right to keep the "before" tone over the flat grey. The only problem was the weird baked texture — and looking inside the model it was two things: false orange/amber colour speckles (the real unit is black + steel, zero colour, so any colour was a baker hallucination) and fine grain. I stripped the artifact colour and smoothed the grain while keeping the original light body + black panels. Same geometry, same tone, clean surface. Drag or let them spin.

Real unit: black + brushed stainless, no colour anywhere — which is why removing the texture's colour is safe.

What to judge

Spin the "after." Is the weird texture gone? Does it keep the brighter "before" tone you preferred (not the dull grey)? The smoothing strength is a single dial in code — I can go smoother or sharper in seconds, or nudge the body slightly more silver-grey if you want it closer to real steel. This GLB is already Shopify "view in your room" AR-ready as-is.
