The MAIN objective of HIPPARCOS was to measure the RELATIVE POSITION AND

besides its  brightness and colors.

Right.
The point with measuring the positions of the stars relative to each
other is that neighbouring stars have the same stellar aberration,
so it is not necessary to compensate for. (The correction is small.)
The angular distances between the neighbouring stars are measured
with a precision of ~1 mas. The sky is scanned over and over at
different times of the year so that the distances between
the same stars are measured many times.
Change in the distances between the stars can be caused by:
1. Proper motion. (A constant angular velocity)
2. Parallax. A yearly change in the position.
3. Gravitational deflection of the Sun. A daily change in position.

Post-procession of the data is obviously a formidable task.
But even you should be able to understand that it is possible
to find:
The position of each star.
The proper motion of each star.
The parallax of each star. (Distance.)
The gravitational deflection of some of the stars.

..and their displacements due to stellar aberration. The precision of
Hipparcos's measurements were such that stars even a fraction of a
degree different in declination would follow measurably different
Bradley ellipses (or rather, overlapping Bradley ellipses from the
spacecraft's orbit around the Sun and its orbit around the Earth.)

The global displacements due to stellar aberration and gravitational
deflection, and the individual displacements due to parallax and
proper motion all needed to be taken in account.

Hipparcos' mission was most decidedly NOT to "prove relativity right".
Rather, adjustments of stars' measured positions due to general
relativistic effects were among the corrections necessary to minimize
the residuals. Otherwise it would have been IMPOSSIBLE to combine the
data measured over a period of years into a consistent map.

Nothing was assumed.
When the position of a star was known at different times of a day,
the difference could only be caused by gravitational deflection.

I would put it somewhat differently. Gravitational deflection was
_corrected for_, otherwise the data simply wouldn't make sense.

Sort of like, particle accelerators don't measure special
relativistic effects. Rather, special relativistic effects must be
taken into account, otherwise analysis of particle trajectories
don't make sense.
This seems reasonable.
After "Revisit Heisenberg, Hubble, Higgs" then another touch-stone
is the Stern-Gerlach experiment, which some say "establishes the
particulate granularity or the quantum" while when Feynman sets it
up in his lecture notes it's "... as would befit a field theory, ...",
establishes continuum mechanics.
The OPTICAL here is key as with regards to both gravitational lensing,
and also large-body lensing. For example, the camera obscura, shows
that a pinhole is a lens, and there's also that simply rolling up a
piece of paper and looking through that, results OPTICAL merely
the wave-guide.
Light: is geometric and OPTICAL, and, "electromagnetic radiation",
has that optical light is special and that optical and radionuclear
radiation are _different_ than electrical field electromagnetic radio
waves.
The Nancy Roman wide-screen will be giving some more wide-field
correlations, while James Webb has thoroughly paint-canned 20'th c.
cosmology.
