Thanks for the shout-out, Ham! I was out in the yard all day, and grocery shopping, after being in a canoe all day Saturday.
Hi & welcome, Aschnak ! One fun thing about buying a plant with an Exotic Angel tag (now a division of Costa Farms,) is that almost all are pictured on their website. Just one pic, but if you know the genus, the species or cultivar is usually easy to determine from there.
If we look at their page for Peperomia, I think yours must be a very new introduction because it does not seem to match any of the plants listed there:
It may be some form of P. orba, but the variegation is different from what I've seen before, so it probably has a cultivar name or at least a for-sale name.
I don't know how reliably they respond to questions sent to their email from their website, but Justin Hancock on their Facebook page definitely responds to any questions posed there. If you put your pics on Exotic Angel FB page, he will probably provide some interesting info within the following 24 hours, assuming he does not happen to be on vacation or otherwise unable to respond.
...but it's not necessary to track down a name so specific to know how to care for it. Peps like the same thing, some direct light in the morning or evening, shade during the intense rays & heat of the day, and being watered before the soil completely dries, but not kept constantly soggy.
