I didn't find a thread at RC, nor a CCF file. I did find a JP1 file for a "Samsung DTB-H260F ATSC tuner" that matches your signals. The JP1 file is here:
[Link: hifi-remote.com]

The table of function_number -> function_name within that file is the only thing that would be of interest to a non JP1 user, so I extracted that here:

0 -> 1
1 -> 2
2 -> 3
3 -> 4
4 -> 5
5 -> 6
6 -> 7
7 -> 8
8 -> 9
9 -> 0
10 -> vol up
11 -> vol down
12 -> channel up
13 -> channel down
15 -> GUIDE
16 -> up arrow
17 -> down arrow
18 -> left arrow
19 -> right arrow
20 -> enter
21 -> EXIT
27 -> FAV CH
30 -> power
32 -> mute
33 -> INFO
34 -> GREEN BUTTON
35 -> ORANGE BUTTON
36 -> BLUE BUTTON
37 -> MENU
38 -> RED BUTTON
48 -> PRE CH
49 -> MTS
50 -> FREEZE
52 -> CAPTION
54 -> CH LIST
55 -> TIMER
57 -> ANTENNA
58 -> ASPECT
59 -> - (dash)

Here is a JP1 thread about converting this code set for use in an MX-700. Maybe you'll find something helpful there.

I don't see any indication in any of the connected files or threads than anyone tested for signals that were not on the original remote (any function numbers 0 through 255 that are not in the above list but which do something useful to the device).

Looking closer now, I see your file already includes differences from that list. Your file has:

30 On/Off
53 Audio
27 FavCH
49 Alt
50 Freez
52 Subtl
51 Text
36 Blue
35 Yellw
34 Green
38 Red
55 Timer
43 TV-RA
54 C.Lst
56 P.Siz
44 RETRN
