there are various types of warps, but I would classify them to playable and unplayable.
Bowl-warp is more-likely playable with screw-on clamp only on one "bottom" side. The other side of bawl-warp is going to slide your stylus possibly damaging both vinyl surface and cantilever
If there's warp with creasing, definitely no go.
I've got one of the later pressings of Bill Evans and exchanged this record twice all the time with some degree of warp.
A playable warp would be the one not going too extreme
