Tiles and paint, maybe.

But cabinetry usually subcon out to cabinet specialists, so developer won't have the materials

Built in cabinetry that come with projects are usually modular type with standardized sizing, they'll cut the parts off site and and then only delivery what they require to the project site. More cost effective this way and can make in bulk.

Unlikely they'd have pieces of board lying around for extra to use, because they can also just use the boards in future projects since most houses these days are standard sizing.

Honestly if you want to DIY cabinet and you have the carpentry skills, just buy materials directly from wood supplier. You don't have to deal with any profit margin trying to buy from the cabinet specialists.

Typically cabinet retailers source from same group of manufacturer/factory, and it's usually quite easy to replicate/make similar or even get same colors/finish. You won't be the first/last person to get additional cabinets to match existing ones, after all 🤭

For bench top/surface it's better to instead look into who's the subcon if you're hardworking enough to research and get from them (Example: Signature Berhad usually publish their project range in their annual reports and their design usually pull from existing Signature colors and surface, or if you're close with the sales agent you can ask them about the brand of the carpentry), or go to a more reputable cabinet maker that has wide range of colors and materials.
