While parts of that are most definitely true (environment/screen) at the same time there are often common settings and factory pre-sets with every display that obtain better than OotB results.
For example with DLP there are often common brightness settings where the DMD dither vanishes and there is usually a common sharpness setting that is optimal without adding ringing/ee (providing a firmware revision has not changed these factors).
Contrast (color shift) can be very screen dependent but there is also often a common setting that most will likely find optimal with matte white screens (or those sharing a similar environment and screen, like white walls with an HP screen).
Now when it comes to CMS settings those can at times be shared and obtain better than OotB settings with projectors that are not initially accurate (unlike the w1070 which is claimed to be pretty good OotB) but these settings should ideally be done in the room and on the screen that the end-user will be viewing (for optimal results).
However with lamp based projectors this is mostly a moot point since there is drift as the lamp ages and even a highly accurate initial CMS calibration is not likely to be nearly as accurate just a few hundred hours later (often times even less).
My offer to calibrate a w1070 is still out there for anyone very close to the Portland Oregon area (at about 1/3 the standard ISF rate), you'll want to get some hours on that lamp before hand though.
* I see below that Doug offered up the same type of calibration and I think I can say that like me he does this for fun as a hobby and for the opportunity to view more projectors, I don't think either of us is looking to make this a career.

If the cost of the ISF certified tech/calibration is not a factor then by all means hire a pro, they will have you seeing your display at its full potential.
