With the possible exception of the rapidly disappearing CRT HDTVs, all
digital TVs must convert any accepted input to the TVs native
resolution. Depending on the native resolution of the TV and the
incoming signal, the conversion could involve up conversion or down
conversion. Since all HDTVs have resolutions that exceed DVD
resolution, all HDTVs must up convert the output of standard DVD
players and any other SD sources.

I suspect that "s video Dish looks like crap compared to OTA HD"
because one is relatively highly compressed SD fed to the TV via an
analog SD-only s video connection, while the other is relatively
lightly compressed HD. The degree of "crapiness" depends on the
amount of compression in the Dish feed and the ability of the TV to
upconvert an analog SD signal.

I realize that some HDTVs have a "1:1" setting that displays inputs
without scaling (at least in theory). Using the "1:1" setting can be
quite enlightening. That "s video" signal will be just a small
rectangle in the center of a big black screen.

So, if "upconversion is great" for you, then (probably) you have a
good external upconverter and your TV's native upconverting is
relatively poor. In a case like yours, external upconverting makes
good sense. However, a real HD source, such as a Blu-Ray disk, should
always look better than the equivalent upconverted SD source; there is
simply more detail to display. How much of the extra detail you can
see depends on the quality of your TV, how large the TV is, and how
far you sit from the TV (and how good your eyes are).

Whether or not you want to pay for the added detail, as always,
remains your perogative. Some are willing to pony up the dollars
today. Some will wait for tomorrow. And some may never find it
necessary.
