You can have minor head gaskets leak that a compression test won't even pick up. And a few other things can cause low compression, leaking valve, gaps in rings not staggered, wrong size pistons, cracked head, etc.
There's really no such thing as a harmless overheating scenario. Every overheat over compresses the head gasket and increases the chances of failure and leakage.
Since you have a reman engine it has heat tabs on the head /block to show overheating that melt about 240-260 F. Visually verify that overheating has occurred is simple. This is used by the manufacturer to deny responsibility for failure caused by things that are due to other people, or systems.
This kind of scenario is why installers give a warranty that's in addition to the engine manufacturers warranty. Typically 12-month one year from reputable install shops. May or may not have been transferrable if shop installed. If po installed it, theres none.
Ordinarily a newly remanufactured engine would be worth repairing. However, if it's been overheated during break-in ....that brings some questions into play about long term effects on engine reliability.
Should you worry about it? Umm...yeah.
It comes down to do you want the truck.
If you do drop the pan on the transmission and see if there's any chunks of metal in there. If there's no chunks of metal good fluid, and only light silt, and no plug, you can feel pretty good about the condition of the transmission probably. If there's chunks of metal or transmission show this never been serviced that that would be concern. You likely don't want to sink $3,000 into engine repair and then turn around and find out you got to pay 2000 plus for a transmission next year also.
other big ticket items...tires, brakes, ball joints, ac compressor. These things add up to thousands of dollars if they need work. Only you can decide if it's worth it to you to keep the truck. At the time I put another engine in my truck I spent $7,000 (tires, brakes, ball joints, engine, stereo, rear view camera, interior fixes) It's been almost 3 years /53,000 mi, and I only spent $165 for a new alternator since. My gamble paid off . So far.

This sounds quite suspicious.
Regardless overheating would void any mfg warranty. Not their problem unless water pump /oil pump came with engine and failed. The chances of having a head gasket leak on a new engine that caused the overheating is extremely low. The engine was computer spin checked for compression before it was shipped.

What's your compression #s? What's slightly low? All cylinders should be within 10% of each other. If you're within that spec than by the standards your engine is ok (compression wise that is)

I have removed the duplicate threads with no replies and merged the two with replies. OP keep it to one thread so the forum doesn't get cluttered and it's not as confusing.
