Any unlockable skins in Gears 4?

Since Gears 5 has been released more often then not I’ve been finding myself going back to Gears 3 & 4. Which brings me to the question, are there any skins that are currently unlockable in Gears 4 that can be obtained or is it a chewed bone for people like myself who don’t think Gears 5 is true to its title and makes the previous installments more enjoyable.

All the skins that were in Gears of War 4 are still there, both free and paid, so if you want to keep unlocking them you can.
