Hello
Compressiontest with added oil can check the rings. A leak down can determine the exact problem.
On a testdrve you can roughly check if it is caused by the head / valve steam seals or from the piston rings.
As you descripe it i would be surprised if the rings where involved much. Yet milage doesn´t hurt a engine. Coldstart are the major wear issues on a engine especially if the driver pushes the pedal while cold and drives to short for a internal even heat up.
