WELCOME to the Forum....
With all the oiling you've done my thought would be greasy feeling and soaked leather is what you have....
Do you have a saddleshop nearby that does repairs?
Or a older cobbler, aka shoemaker shop where you could take the saddle for evaluation of what you are doing to the leather thinking you are scrubbing dirt gone...
Now saying colors are changing and you think its the tanning process....quality saddles do not lose their tanning easily makes me say slow down and get some true help from those who know leather, leather quality and how tanning is done and by what method.
To dye a saddle, many make a comment like its real easy....
Ever do leather dyeing before?
Are you sure you want to be the one to dye the saddle so it looks uniform everywhere or are you figuring to "spot" dye and think it will match???
Saddleshop or a cobbler who has been around cause they also often see horse tack and have worked on it would be where I would go before anymore cleaning takes place...
Those professionals can also advise you on what products to use specifically since different products indeed interact differently with different tanning processes and so do dyes...
Saddles need sparse oiling....aka not often
They need to be wiped off of dirt and filth with a soft cloth more than anything.
A cleaning only as needed with saddle soap or what that saddle tanning process reacts best with sparingly and no soaking of leather with oils or anything else...not the way you mean it or make it sound.
Leather is a breathing product and coating it in layers of oil and solvents ruins it and shortens its life and safety for us using it....yes, you can rot leather. And although harder today because thread is polyester or nylon twisted and cotton...to wet/greasy does have a adverse effect on that too...
Its not a simple answer to what do you do...
If me, with what you are describing I would be off to a professional and after a evaluation make some changes or indeed let the professional clean and save my saddle, even dye it so it has a sameness you have stolen in appearance.
I wish you good luck.
