I would say that typically, factory loads with smokeless powder are not compressed.
Smokeless powder is manufactured with a particular burning rate for each type or number of powder. Generally, powder with a faster burning rate is used in smaller capacity cases, and a powder with a slower burning rate is used in larger capacity cases or with heavier bullets.
Reloading manuals list a variety of powders for each weight of bullet for each cartridge. My Hornady 8th edition reloading manual lists 18 different powders for loading 150 gr bullets in the .30-06 cartridge. These listed loads vary from less than 40 grains of A 2495 powder to over 60 grains of H 4350 powder.
60.5 grains of H 4350 powder in a .30-06 case is just about level with the case mouth, and would definitely be a compressed load. You might be able to safely work up to that load in your .30-06.
In that same manual, the maximum listed weight of A 2495 powder is less than the minimum listed weight of H 4350 powder for the 150 grain bullet in a .30-06. A compressed load of A 2495 powder with that bullet in a .30-06 would be very dangerous, and would probably blow up your gun.
Not all reloading manuals identify compressed loads. MY Hornady 8th edition and Barnes No 4 do not, Nosler 5th edition does.
