Warped records must be graded as warped by the seller, just don’t buy warped records, instead you can find same release is better condition (almost always).
Put the record on the platter and rotate it watching the edge of the record (side view on the platter) and you will see. Minor warp (a few millimetres) is irrelevant, records are not perfect. If you see more than 5mm warp just don’t buy it.
Cartridge can play warped record, some high compliance MM can play totally warped records without skipping.
You Dynavector can play slightly warped records.
