Question: Glacial Frost Finish on Majesties

For those who have owned or have seen Glacial Frost Majesties, does that matte white tend to fade to a buttercream/vintage-y colour over time? My White JP7 did but it wasn’t really ever bright white to begin with, anyway.

Suppose it may not be possible to say given they’re only a few years old at this point but I’m curious since I’m looking to pick one up in the near future.
