I know and it would be pretty hard for Keto meals to not become palatable due to all the fat.
Long term all weight loss diets are equally disappointing, because appetite does come back and compliance becomes an issue. At maintenance we can actually tolerate a lot, esp if we are lightly active, but if you want to lose weight, striving for better tasting food is a poor strategy.
An excelent book on this subject is "The Hungry Brain" by Stephan Guyenet:

This guy's blog is awesome too and if you're interested for example into why the "carbohydrate insulin model" is wrong, checkout this list of references produced by him:

We have a brain hard-wired to seek foods high in calories and salt and we also prefer diversity. People on keto when looking at sweets, like brownies, they see the carbs, however the bigger problem is the fat + refined carbs combination. All junk food is a combination of fat + refined carbs, because this is a recipe for making the food hyper-palatable. This goes for French fries too, it's not the actual potato, because potatoes have a lot of water, a lot of volume and if you eat them boiled, few things are as satiating. Combine potatoes with fat by deep frying, then add some salt and both calories and palatability goes through the roof.
How can you make veggies and greens, like spinach or brocoly, tasty? You add some fat. Incidentally this is how you can trick your brain to like greens.
Most people have issues losing weight while eating brownies, not because you can't lose weight when eaten in moderation, but because it's so hard to not binge on brownies, especially if you have emotional issues too (and many overweight people have emotional issues), foods like brownies being perfect as a comfort food. You can binge on fruits, veggies, lean meat or beans of course, but it doesn't have the same impact.
(N.b. I love brownies, brownies are awesome, they just aren't good to have around when losing weight)
People in the keto community talk about carb cravings, however there is such a thing as craving fat or any food high in calories too, because it's not really about any particular macro nutrient. When I was on keto, I used to binge eat plain full fat butter. I also used to eat 1 Kg of grilled pork chops in a single seating and then I was hungry again at the next meal.

On the whole however, both low carb diets and low fat diets lead to a spontaneous loss in appetite in many people. It's why they work short term.
This doesn't necessarily last for long, because you get used to what you eat and because we tend to diversify our meals in our search for better tasting food. Then the dreaded plateau appears, which can happen pretty fast on keto, esp due to the propaganda that calories don't matter.
Such diets are still better than the SAD, but you'd get a similar bang for the buck in terms of satiety and healthfulness ... if you just stuck with whole foods at least 80% of the time.
