And what is x$ktfbue and how it is maintained if there is no info in data dictionary?

Yes, they show up in dba_extents, but it doesn't come from sys.uet$.

Here's the view as of 8.1.7. Extents in LMT's are retrieved by the second SELECT statement in the SQL.

select ds.owner, ds.segment_name, ds.partition_name,

        ds.segment_type, ds.tablespace_name, e.ext#, 
        f.file#, e.block#, 
        e.length * ds.blocksize, e.length, e.file#

from sys.uet$ e, sys.sys_dba_segs ds, sys.file$ f where e.segfile# = ds.relative_fno

        and e.segblock# = ds.header_block
        and e.ts# = ds.tablespace_id
        and e.ts# = f.ts#
        and e.file# = f.relfile#
        and bitand(NVL(ds.segment_flags,0), 1) = 0

union all -- get the LMT extents
select /*+ ordered use_nl(e) use_nl(f) */

        ds.owner, ds.segment_name, ds.partition_name, 
        ds.segment_type, ds.tablespace_name,
        e.ktfbueextno, f.file#, e.ktfbuebno,
        e.ktfbueblks * ds.blocksize, 
        e.ktfbueblks, e.ktfbuefno

from sys.sys_dba_segs ds, sys.x$ktfbue e, sys.file$ f where e.ktfbuesegfno = ds.relative_fno

        and e.ktfbuesegbno = ds.header_block
        and e.ktfbuesegtsn = ds.tablespace_id
        and e.ktfbuesegtsn = f.ts#
        and e.ktfbuefno = f.relfile#
        and bitand(NVL(ds.segment_flags, 0), 1) = 1
