Put up a new soffit. It is impossible to make waste pipes look attractive in a home situation, especially in a food preparation area. Add sound insulation in the soffit.

^ agree - that was a soffit doing its job, not sure they are a lot of other options, maybe a photo from further back?

Maybe a carpenter could build a soffit that looks like a cabinet

Like this.

Advice for hiding a soffit

I'd get a plumber in to see if you can keep the 3" left 90 from dropping. Take it and the trapped 2" down to the main stack before tying back in. At least the new soffit would be smaller.

This is what it looks like from afar. There are no cabinets in that corner. nor are there any (except couple of floating shelves) on the left of the door.

not sure if i should take that soffit all the way across the door or just stop half way

A plain soffit will look fine, no need to add “cupbaord style doors” unless you feel you may need to access that plumbing and if the scenerio happens you will probably cut drywall anyway. Do not add brick. You design aesthetic will be revealed in other areas of the room, not above door frame.

Stopping the soffit halfway will call even more attention to the problem. Continue it all the way across. Paint your wall and ceiling the same color and forget about it.

Don't stop the soffit half way across. A soffit that is a complete shape will look more intentional.

I live in a row house with masonry walls and some soffits are necessary. I had one that ran the width of the LR and was the width of the basement stairwell enclosure.

When we took the ceiling down in that area it was 90% empty with a pipe and a duct hanging down in one corner.

Some people just boxed out that little corner and I think it looks worse having a little box hanging down in one spot.

Yours would be so obvious boxed out hanging over the middle of the door and stopping. At least if it goes all the way across it will look "structural" somehow.

Carry it all the way across and paint the same color as the walls. Over time, you will never look at it again. Just have it built as small as possible.

This kitchen had that kind of pipe halfway above the slider and it carried across to the cabinet on the right side of the stove hood! Soffit was very overbuilt so we were bale to make it much smaller.

I like Boxerpals idea to make the soffit look like cabinets. If you could use more storage, continuing the cabinets down either side of the sliding door might be very useful. I couldn’t find closed upper cabinets for the mock-up, but this is the general concept. I’ve left open wall space beside the doors for stacked drapes.
