Picture?

To clarify, the crown on the sides of the refrigerator enclosure do not meet at the corners properly.

If your concern is that thin seam where the two pieces meet at the corner, that can readily and legitimately be fixed with a small amount of white painters caulk. And you'll never notice it.

Even if you couldn't see the seam now, it's possible that it could open up over time. Caulk has flex to it and can help hide seasonal variations in wood moldings as they shrink and expand with the seasons and changes of humidity.

Clarified, it doesn't look correct because it isn't. This is a case of inside and outside mitres, done incorrectly. Basically he needed to use both, inside and outside mitre and did not.

Wrong

You want the line up...........with the cabinet frame.

Call a pro trim guy, Your cabinet installer is not that. Style of trim makes no difference......

With overlay doors things like this come up because the doors sit in Front of the cabinet, covering the cabinet box and panels are usually considered part of the "box". So there are two different conditions, and you want the trim to look the same on both. To do that here, the trim would have to be recessed flush with the panel so it looked the same as being flush with the overlay door.

I would ask your cabinet installer to redo that section. The moulding shouldn't stick out that far.

There are a thousand ways to do this on u tube

Here's one. Easier? Get a pro trim guy. : )

It can be done far far better.

Thank you, everyone, for your responses. I will be contacting a trim guy.

That video posted is the exact same thing that the OP has (except with a smaller reveal) and is the reason that the cabinets look bad. With frameless cabinets you typically add a bigger reveal over doors than you do over frame or side panels. So the reveal on the front is typically 3/4" and the reveal at the sides is either flush or less than 3/8".

Here is a great example of a proper reveal on a frameless cabinet with a similar set up to the OP This is a stacked crown and the OP doesn't need that, but the reveals are done properly.

Notice how if the doors are open the crown would appear much larger on the front. That is because the reveal is pulled out in the front to align with the doors rather than the box. This is what should be done when the side panels are pulled flush with the doors giving an inset appearance. Alternatively, if the side panels are not pulled flush with the doors, you can add some height and use a standard reveal but you want the crown a bit above the doors then to add separation.

Note: I am not a fan of the job itself as I wouldn't have the gap at the top either... but the reveal is done well.
